This relands e9a3d1a401b07cbf7b11695637f1b549782a26cd which was originally
missing linking LLVMSupport into LLMVFileCheck which broke the SHARED_LIBS build.
Original summary:
The actual FileCheck logic seems to be implemented in LLVMSupport. I don't see a
good reason for having FileCheck implemented there as it has a very specific use
while LLVMSupport is a dependency of pretty much every LLVM tool there is. In
fact, the only use of FileCheck I could find (outside the FileCheck tool and the
FileCheck unit test) is a single call in GISelMITest.h.
This moves the FileCheck logic to its own LLVMFileCheck library. This way only
FileCheck and the GlobalISelTests now have a dependency on this code.

Add printf-style precision specifier to pad numbers to a given number of
digits when matching them if the value is smaller than the given
precision. This works on both empty numeric expression (e.g. variable
definition from input) and when matching a numeric expression. The
syntax is as follows:
[[#%.<precision><format specifier>, ...]
where <format specifier> is optional and ... can be a variable
definition or not with an empty expression or not. In the absence of a
precision specifier, a variable definition will accept leading zeros.

Substitutions are already reported in the diagnostics appearing before
the input dump in the case of failed directives, and they're reported
in traces (produced by `-vv -dump-input=never`) in the case of
successful directives. However, those reports are not always
convenient to view while investigating the input dump, so this patch
adds the substitution report to the input dump too. For example:
```
$ cat check
CHECK: hello [[WHAT:[a-z]+]]
CHECK: [[VERB]] [[WHAT]]
$ FileCheck -vv -DVERB=goodbye check < input |& tail -8
<<<<<<
1: hello world
check:1 ^~~~~~~~~~~
2: goodbye word
check:2'0 X~~~~~~~~~~~ error: no match found
check:2'1 with "VERB" equal to "goodbye"
check:2'2 with "WHAT" equal to "world"
>>>>>>
```
Without this patch, the location reported for a substitution for a
directive match is the directive's full match range. This location is
misleading as it implies the substitution itself matches that range.
This patch changes the reported location to just the match range start
to suggest the substitution is known at the start of the match. (As
in the above example, input dumps don't mark any range for
substitutions. The location info in that case simply identifies the
right line for the annotation.)

This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds support for specifying the
matching constraint for a numeric expression, ie. how the value being
matched should relate to the numeric expression.
This commit only adds the equality constraint where the numeric value
matched must be equal to the numeric expression. It is the default
matching constraint used when not specified. It is added to provision
other matching constraint (e.g. inequality relations).

This patch extends numerical expressions to allow calls to
predefined functions. These calls can be combined with the
existing numerical operators, which includes nesting calls.
The call syntax is:
<func>(<args>)
Where <func> is a predefined string literal, currently limited to
one of add, max, min and sub. <arg> is a comma seperated list of
numerical expressions.

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds support signed numeric
values, thus allowing negative numeric values.
As such, the patch adds a new class to represent a signed or unsigned
value and add the logic for type promotion and type conversion in
numeric expression mixing signed and unsigned values. It also adds
the %d format specifier to represent signed value.
Finally, it also adds underflow and overflow detection when performing a
binary operation.

With this change it is be possible to write FileCheck expressions such
as [[#(VAR+1)-2]]. Currently, the only supported arithmetic operators are
plus and minus, so this is not particularly useful yet. However, it our
CHERI fork we have tests that benefit from having multiplication in
FileCheck expressions. Allowing parenthesized expressions is the simplest
way for us to work around the current lack of operator precedence in
FileCheck expressions.

D79276 caused the following builder to fail:
http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win/builds/23489
Specifically, FileCheck dumped stack in the following tests:
LLVM :: MC/Mips/micromips-jump-pc-region.s
LLVM :: MC/Mips/mips-jump-pc-region.s
Those tests contained characters encoded as 160 but that render (at
least for me in vim) like a single space (32). Those characters
appeared between the `#` and `RUN:` on several lines, and D79276
caused FileCheck to process those lines differently: `RUN:` is a
comment directive. As a result, D79276 caused FileCheck to start
calling is `isalnum` on those characters.
The problem is that FileCheck calls `isalnum` on type `char` without
casting to `unsigned char` first, so it sign-extends 160 beyond what
`unsigned char` or `EOF` can represent. C says that has undefined
behavior. This problem is general to FileCheck's prefix parsing and
so exists independently of D79276.
524457edbc3d fixed the above tests. This patch changes FileCheck to
use LLVM's replacements for `ctype.h` functions, and it adds tests for
cases that are representative with or without D79276.

Sometimes you want to disable a FileCheck directive without removing
it entirely, or you want to write comments that mention a directive by
name. The `COM:` directive makes it easy to do this. For example,
you might have:
```
; X32: pinsrd_1:
; X32: pinsrd $1, 4(%esp), %xmm0
; COM: FIXME: X64 isn't working correctly yet for this part of codegen, but
; COM: X64 will have something similar to X32:
; COM:
; COM: X64: pinsrd_1:
; COM: X64: pinsrd $1, %edi, %xmm0
```
Without this patch, you need to use some combination of rewording and
directive syntax mangling to prevent FileCheck from recognizing the
commented occurrences of `X32:` and `X64:` above as directives.
Moreover, FileCheck diagnostics have been proposed that might complain
about the occurrences of `X64` that don't have the trailing `:`
because they look like directive typos:
<http://lists.llvm.org/pipermail/llvm-dev/2020-April/140610.html>
I think dodging all these problems can prove tedious for test authors,
and directive syntax mangling already makes the purpose of existing
test code unclear. `COM:` can avoid all these problems.
This patch also updates the small set of existing tests that define
`COM` as a check prefix:
- clang/test/CodeGen/default-address-space.c
- clang/test/CodeGenOpenCL/addr-space-struct-arg.cl
- clang/test/Driver/hip-device-libs.hip
- llvm/test/Assembler/drop-debug-info-nonzero-alloca.ll
I think lit should support `COM:` as well. Perhaps `clang -verify`
should too.

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds support for selecting a
matching format to match a numeric value against (ie. decimal, hex lower
case letters or hex upper case letters).
This commit allows to select what format a numeric value should be
matched against. The following formats are supported: decimal value,
lower case hex value and upper case hex value. Matching formats impact
both the format of numeric value to be matched as well as the format of
accepted numbers in a definition with empty numeric expression
constraint.
Default for absence of format is decimal value unless the numeric
expression constraint is non null and use a variable in which case the
format is the one used to define that variable. Conclict of format in
case of several variable being used is diagnosed and forces the user to
select a matching format explicitely.
This commit also enables immediates in numeric expressions to be in any
radix known to StringRef's GetAsInteger method, except for legacy
numeric expressions (ie [[@LINE+<offset>]] which only support decimal
immediates.

Summary:
The Regex "match" and "sub" member functions were previously not "const"
because they wrote to the "error" member variable. This commit removes
those assignments, and instead assumes that the validity of the regex
is already known after the initial compilation of the regular
expression. As a result, these member functions were possible to make
"const". This makes it easier to do things like pre-compile Regexes
up-front, and makes "match" and "sub" thread-safe. The error status is
now returned as an optional output, which also makes the API of "match"
and "sub" more consistent with each other.
Also, some uses of Regex that could be refactored to be const were made const.

Summary:
Commit r366897 introduced the possibility to set a variable from an
expression, such as [[#VAR2:VAR1+3]]. While introducing this feature, it
introduced extra logic to allow using such a variable on the same line
later on. Unfortunately that extra logic is flawed as it relies on a
mapping from variable to expression defining it when the mapping is from
variable definition to expression. This flaw causes among other issues
PR42896.
This commit avoids the problem by forbidding all use of a variable
defined on the same line, and removes the now useless logic. Redesign
will be done in a later commit because it will require some amount of
refactoring first for the solution to be clean. One example is the need
for some sort of transaction mechanism to set a variable temporarily and
from an expression and rollback if the CHECK pattern does not match so
that diagnostics show the right variable values.

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch lift the restriction for a
numeric expression to either be a variable definition or a numeric
expression to try to match.
This commit allows a numeric variable to be set to the result of the
evaluation of a numeric expression after it has been matched
successfully. When it happens, the variable is allowed to be used on
the same line since its value is known at match time.
It also makes use of this possibility to reuse the parsing code to
parse a command-line definition by crafting a mirror string of the
-D option with the equal sign replaced by a colon sign, e.g. for option
'-D#NUMVAL=10' it creates the string
'-D#NUMVAL=10 (parsed as [[#NUMVAL:10]])' where the numeric expression
is parsed to define NUMVAL. This result in a few tests needing updating
for the location diagnostics on top of the tests for the new feature.
It also enables empty numeric expression which match any number without
defining a variable. This is done here rather than in commit #5 of the
patch series because it requires to dissociate automatic regex insertion
in RegExStr from variable definition which would make commit #5 even
bigger than it already is.

Summary:
Commit r365249 changed usage of FileCheckNumericVariable to have one
instance of that class per variable as opposed to one instance per
definition of a given variable as was done before. However, it retained
the safety check in setValue that it should only be called with the
variable unset, even after r365625.
However this causes assert failure when a non-pseudo variable is being
redefined. And while redefinition of @LINE at each CHECK line work in
the general case, it caused problem when a substitution failed (fixed in
r365624) and still causes problem when a CHECK line does not match since
@LINE's value is cleared after substitutions in match() happened but
printSubstitutions also attempts a substitution.
This commit solves the root of the problem by changing setValue to set a
new value regardless of whether a value was set or not, thus fixing all
the aforementioned issues.

Summary:
Processing of command-line definition of variable and logic around
implicit not directives both reuse parsing code that expects a line
number to be defined. So far, a special line number of 0 was used for
those users of the parsing code where a line number does not make sense.
This commit instead represents line numbers as Optional values so that
they can be None for those cases.

Summary:
This patch simplifies 2 aspects in the FileCheckNumericVariable code.
First, setValue() method is turned into a void function since being
called only on undefined variable is an invariant and is now asserted
rather than returned. This remove the assert from the callers.
Second, clearValue() method is also turned into a void function since
the only caller does not check its return value since it may be trying
to clear the value of variable that is already cleared without this
being noteworthy.

Summary:
The value of the FileCheckNumericVariable class instance representing
the @LINE numeric variable is set and cleared respectively before and
after substitutions are made, if any. However, when a substitution
fails, the value is not cleared. This causes the next substitution of
@LINE later on to give the wrong value since setValue is a nop if the
value is already set. This is what caused failures after commit r365249.
